TP3’ Calibration

The TP3’ is mandatory for all devices to ensure tolerances are met at the defined reference plane. Tektronix USB4 Receiver Test wizard will guide the user through all the necessary steps as per the specification requirements to ensure future calibration steps complete with ease. Some of the test parameters are used in TP3 calibration that is needed to complete the stressed eye tests.
